PubMed Health is a resource for clinical effectiveness research. With over 5,000 systematic reviews, PubMed Health goals are to help users find evidence that could answer their questions about the effects of health care and help them understand what they find.
Systematic reviews have been scattered widely on content providers’ websites without being centrally collected. The PubMed Health initiative is gathering them together within a single searchable resource. The review and review summaries now in PubMed Health account for perhaps one-third of the good quality systematic reviews published by public agencies and journals worldwide.
